I have a Bayou 300 4x4. It idles fine and seems to rev fine when in neutral. But once I put it in gear and give it throttle it will surge. It will accelerate then stop,,accelerate then stop like if i was giving it throttle and then letting off. Fuel flow from the tank to the carb is good. Suggestions please

Thanks

Purchase a carb kit....clean the carb and rebuild it.
